The Edelweiss Above The Tree Line site has a listing of The Rift Library Edition. The cover features Aang and Toph in a factory with a mysterious samurai-like entity behind them. I always enjoy reading the commentaries at the side of the comics in the library edition along with concept art of the comic.

This book is slated to be released on February 24 2015 next year. It is not listed for pre-order on Amazon at the moment but we will update this post once we have a link to it. So if you have not bought the individual volumes of The Rift yet, maybe you can save up for this hardcover library edition.
